Description

BACKGROUND ART Assembled structure of aluminum curtain wall < RTI ID = 0.0 >

The present invention relates to a curtain wall, and more particularly, to a curtain wall capable of precisely fastening a screw for fixing a glass panel to a center of a joining site of an aluminum structural member, thereby preventing rain water leakage and deterioration of appearance, Moon < / RTI >

In recent modern architectural style, curtain walls (windows) are used to block the rain and wind from the outside, to block noise and heat, and to prevent the pillars and beams from being exposed to the outside. curtain wall) method is attracting much popularity.

A curtain wall is a name attached to a building because it acts only as a curtain that divides a space in a structure that supports a vertical load applied to a building and a horizontal load caused by a wind or an earthquake by only a frame of a main structure of a building and a frame of a beam, It is also called the "strength partition wall". As the outer wall panel for curtain wall, a glass panel which is a typical exterior material is mostly used, and in order to prevent heat loss, double glass or heat ray absorbing glass is mainly used.

The curtain wall is used to block rain or wind from the outside and to block noise and heat, and the column and the beam are not exposed to the outside, and the wall using glass or the like has a large function as the exterior. Especially, it is widely used for high-rise or super-high-rise construction, and it is difficult to assemble scaffolding outside the building with height of 100m or more.

The basic structure of such a curtain wall is composed of a glass panel and a structural material such as a mullion and a transom of steel or aluminum alloy for fixing the glass panel. In addition, since the weight of the glass panel is very heavy, the strength and supporting force of the structural member supporting the glass panel and the supporting member for fixing the glass panel to the structural member are very important.

Patent Document 1 of the following prior art document shows a representative example of a steel curtain wall. That is, Patent Document 1 discloses a steel curtain wall in which a wall of a building is formed of a two-layer glass panel, a steel frame and a bracket of a rectangular cross-section are provided on the inside / outside of the horizontal and vertical connection portions of the double- And is screwed to the steel frame to join the neighboring multi-layer glass panels. Particularly, a dovetail groove is formed in the center of the fixing plate in front of the steel frame in the longitudinal direction, and an á-shaped wedge piece is inserted in the dovetail groove. An inner gasket is provided on both side fixing plates of the dovetail groove, An outer gasket corresponding to the gasket is provided so that the edge of the multilayer glass is abutted between the inner gasket and the outer gasket so that the washer bolt is screwed to the wedge piece inserted into the dovetail groove of the steel frame from the outside of the bracket. The structure of such a conventional steel curtain wall may also be applied to an aluminum curtain wall. However, in such a structure of the curtain wall, it is difficult to accurately fasten a fixing member such as a screw for fixing the glass panel to the center of the joint portion of the frame (i.e., aluminum structural member). Therefore, there is a high possibility that the fixing member for fixing the glass panel is warped in a distorted state at the center portion of the aluminum structural member. As a result, a clearance is generated in the fastening portion, making it difficult to join the outer cover, rainwater may permeate through the gap, and the aesthetic appearance may be damaged. Further, since there is no means for preventing the inflow of cool air between the glass panels, there is a problem that the heat insulating performance is lowered in winter and the rainwater blocking effect is also lowered.

On the other hand, Patent Document 2 discloses an aluminum insulating curtain wall having a structure in which a glass panel is fixed by using a connecting member to an aluminum fixing frame (that is, an aluminum structural member) as shown in Fig. However, since the connecting member is coupled to the aluminum fixing frame by the convex-concave method by the protruding portion and the groove portion, it is difficult to ensure a stable installation state of the glass panel because the bonding strength is reduced. It is also possible to form a predetermined space through the connecting member on the connecting member and to form a predetermined space between the aluminum fixing frame and the cover member on both sides of the connecting member to prevent heat exchange and ensure the heat insulating performance However, it is difficult to expect the heat insulating performance merely by forming the space portion.

As a result, a clearance is generated in the fastening portion, making it difficult to join the outer cover, rainwater may permeate through the gap, and the aesthetic appearance may be damaged. In addition, since means for preventing the inflow of cool air between the glass panels is not provided, not only the heat insulating performance is deteriorated but also the rain water shielding effect is deteriorated. In the aluminum curtain wall as in Patent Document 2, the glass panel is fixed to the aluminum fixing frame by the connecting member which is coupled by the convex-concave method. However, this method has a problem that the bonding strength is low and the glass panel can not be stably installed In order to secure the heat insulation performance through the space formed between the inside of the connecting member and the both sides of the connecting member, there is a problem that the heat insulating performance can not be expected with such a space only.

The second gasket is coupled to the binding groove of the heat insulating material so as to block the cool air and moisture flowing between the second gasket and the glass panels, And a third gasket having a V-notch groove formed in a straight line with the wedge groove of the heat insulating material is provided at a site where the screw for joining is joined.

In the present invention, a locking protrusion may be formed in the coupling groove of the heat insulating material, and the third gasket may be provided with a locking protrusion such that the third gasket is not detached from the coupling groove.

In the present invention, the third gasket may be provided with a closed loop type shock absorber positioned between the glass panel and the heat insulating material.

However, it should be understood that the following embodiments are provided so that those skilled in the art can understand the present invention without departing from the scope and spirit of the present invention. It is not.

FIG. 2 is an exploded view showing an embodiment of the present invention, FIG. 3 is an assembled state sectional view of the embodiment of the present invention, FIG. 4 is an exploded perspective view of an embodiment of the present invention, Fig.

2 to 5, the coupling structure of the aluminum curtain wall illustrated in the embodiment of the present invention includes a structure in which a pair of opposed glass panels 20 are installed on the front portion of the aluminum structural member 10 .

In the following description of the embodiment, the glass panel 20 is disposed on the upper and lower sides of the aluminum structural member 10 while being disposed on the aluminum structural member 10. However, the glass panel 20 is disposed on the left and right sides, It is needless to say that the present invention can be similarly applied to an example in which the structural member 10 is installed.

The first gasket 30 is provided between the glass panels 20 opposed to each other and the front part of the aluminum structural member 10 on which the glass panels 20 are mounted, A second gasket (40) corresponding to the first gasket (30) is provided outside the panels (20). When the glass cap securing screw 60 is attached from the outside of the quick cap 50 to the engaging portion 10a provided on the front portion of the aluminum structural member 10 in the state where the inner cap 50 is provided outside the second gasket 40, Lt; / RTI > A fixing bracket 11 is coupled to the glass panel fixing screw 60 in the aluminum structural member 10 so that the glass panel fixing screw 60 can maintain a firm fixing force with the aluminum structural member 10. [ Respectively.

Reference numeral 70 denotes a panel support for supporting the glass panel 20 and reference numeral 80 denotes a screw head cover for covering the head portion of the glass panel fixing screw 60, Is an 'outer cover' that prevents the glass panel fixing screw 60 from being exposed to the outside.

Such a configuration is a known element that can be seen also in a coupling structure of a conventional steel or aluminum curtain wall. Although the first gasket 30 and the second gasket 40 prevent heat from escaping from the inside to the outside and prevent penetration of rainwater or the like from the outside into the inside, 30 and the second gasket 40 alone, it is difficult to expect sufficient heat insulating performance and moisture barrier performance. Furthermore, it is difficult to accurately fasten the glass panel fixing screw 60 to the center of the joining portion 10a of the aluminum structural member 10. [ Accordingly, there is a high possibility that the glass panel fixing screw 60 is screwed in a state of being deflected from the center of the joining portion 10a of the aluminum structural member 10. Accordingly, a clearance is generated in the joining portion, The rainwater may permeate through the gap, and the appearance may be damaged.

The present invention solves the above problems through the following design changes and additional components.

First, the joining portion 10a provided on the front portion of the aluminum structural member 10 is formed into a concave shape. In addition, the fixing bracket 11 provided in the aluminum structural member 10 also has a shape in which the surface of the aluminum structural member 10 opposed to the engagement portion 10a is in close contact with the engagement portion 10a of the aluminum structural member 10 .

A heat insulating material 100 made of polyamide, which is a PVC-based resin, is provided on the front surface of the aluminum structural member 10. [ The heat insulating material 100 is formed with a seating projection 101 protruding in such a manner as to coincide with the outer periphery of the joining portion 10a on the surface facing the joining portion 10a of the aluminum structural member 10, The projection 101 is stably fitted to the front surface of the aluminum structural member 10 while being fitted to the engagement portion 10a of the aluminum structural member 10. [ The first gasket 30 provided between the front surface of the aluminum structural member 10 and the glass panel 20 is also coupled to the heat insulating material 100. The heat insulating material 100 may be fixed with a fixing screw 120 to securely fix the heat insulating material 100 to the joining portion 10a of the aluminum structural member 10. [

Particularly, when the glass panel fixing screw 60 is coupled to the joining portion 10a of the aluminum structural member 10, the heat insulating material 100 is bonded to the aluminum structural member 10 The wedge groove 102 is formed so as to face the center of the joining portion 10a of the base 10. The wedge groove 102 is formed in a straight line straight toward the center of the joining portion 10a of the aluminum structural member 10 so that the joining portion 10a of the aluminum structural member 10 is fixed to the glass panel fixing screw 60, The sharpened front end portion of the glass panel fixing screw 60 is directed to the center of the joining portion 10a of the aluminum structural member 10 through the wedge groove 102 so that the glass panel fixing screw 60 is fixed to the aluminum structural member 10. [ To be precisely engaged with the center of the coupling portion 10a of the coupling portion 10. The heat insulating material 100 is further provided with a binding groove 103 on the outer side of the wedge groove 102. The following third gasket 110 is coupled to the binding groove 103.

Particularly, the third gasket 110 may be positioned between the upper glass panel 20 and the lower glass panel 20 when the upper and lower pairs of glass panels 20 are disposed, And is positioned between the glass panel 20 on the left side and the glass panel 20 on the right side when the pairs are arranged. This is a configuration in which a gasket is not interposed between glass panels in a conventional steel or aluminum curtain wall coupling structure.

In order to prevent the third gasket 110 from being detached from the coupling groove 103 of the heat insulating material 100, the coupling groove 103 of the heat insulating material 100 is provided with an engagement jaw 103a And the third gasket 110 may be formed with a latching protrusion 111 for latching the latching protrusion 103a.

Particularly, the third gasket 110 may be provided with a closed loop type buffer part 112 located between the glass panel 20 and the heat insulating material 100, Since the glass panel 20 has a structure in which a space is formed therein, it is possible to reduce the impact due to the load of the glass panel 20 disposed on the upper side, ) And the heat insulating material 100 can be blocked.

3, the water penetrated through the upper side gap of the upper glass panel 20 and the second gasket 40 is guided to the lower side of the lower glass panel 20 and the second gasket 40, And a second gasket (40) on the lower side of the second gasket (40) to guide the gasket (40) to be discharged to the outside through the lower side gap of the second gasket (113) may be formed.

When the glass panel fixing screw 60 is coupled to the joining portion 10a of the aluminum structural member 10, the pointed tip of the glass panel fixing screw 60 is inserted into the third gasket 110, Notch grooves 114 for guiding the wedge grooves 102 to the wedge grooves 102 of the heat insulating material 100 and the centers of the joining portions 10a of the aluminum structural material 10 are formed in a straight line have.

The fixing structure of the aluminum curtain wall according to the present invention constructed as in the above embodiment is such that a fixing bracket 11 is provided inside the aluminum structural member 10 in order to fix the glass panel 20 to the front side of the aluminum structural member 10. [ When the glass panel fixing screw 70 is joined to the coupling portion 10a provided on the front surface of the aluminum structural member 10 in a state where the glass panel fixing screw 70 is inserted.

First, when the seating protrusion 101 of the heat insulating material 100 is fitted into the engaging portion 10a of the aluminum structural member 10 and the heat insulating material 100 stably stays on the front surface of the aluminum structural member 10 And is firmly fixed by the fixing screw 120. At this time, the wedge grooves 102 formed in the heat insulating material 100 are aligned with the centers of the joining portions 10a of the aluminum structural members 10 along the joining progress direction of the glass panel fixing screws 70 do.

The first gasket 30 is interposed between the glass panel 20 disposed on the front side of the aluminum structural member 10 and the heat insulating material 100 and the third gasket 30 is disposed in the middle of the glass panel 20, (110) is coupled to the coupling groove (103) of the heat insulating material (100). A second gasket 40 is provided on the outer side of the glass panel 20 and the inner cap 50 is coupled to the outside of the second gasket 40.

In this state, the operator joins the glass panel fixing screw 60 toward the joining portion 10a of the aluminum structural member 10. At this time, the pointed tip of the glass panel fixing screw 60 contacts the inner cap 50 and the second Is guided into the wedge groove (102) of the heat insulating material (100) through the V-notch groove (114) of the third gasket (110) while passing through the gasket (40) As shown in Fig. Therefore, the pointed tip of the glass panel fixing screw 60 can be precisely engaged with the center of the joining portion 10a of the aluminum structural member 10 and the center of the fixing bracket 11.

Thereafter, when the screw head cover 80 is put on the head of the glass panel fixing screw 60 and the outer cover 90 is closed, the operation is completed.

As described above, in the aluminum curtain wall connecting structure according to the present invention, since the glass panel fixing screw 60 is accurately engaged with the center without being warped against the joining portion 10a of the aluminum structural member 10, Problems such as difficulty in joining of the outer cover 90, damage to the outer appearance of the outer cover 90, inflow of rainwater due to the gap, etc., which may occur when the screw 60 is engaged in a distorted state, are completely solved.

In addition, since the heat insulating material 100 is provided between the glass panel 20 and the aluminum structural member 10, the heat insulating performance is improved as compared with the prior art, and in particular, the third gasket 110 is installed between the glass panels 20 So that the cold air that can flow into the glass panels 20 is cut off and the heat insulating performance is remarkably improved. The third gasket 110 is provided with a drain guide portion 113 for guiding rainwater or the like flowing between the second gasket 40 and the glass panel 20 to be discharged to the outside, The inflow of rainwater to the side of the structural member 10 can be effectively excluded.

Meanwhile, FIG. 6 shows the result of the insulation test for the joining structure of the aluminum curtain wall according to the present invention. Thermal infrared images of the head, vertical, and sill regions of the structure show that the outer side of the glass panel has a low blue color, whereas the glass panel And the aluminum structural member are colored with yellow and red colors having a high temperature. Thus, it can be seen that the heat insulating effect according to the present invention is excellent due to the application of the heat insulating material 100, the third gasket 110, and the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, This is possible.
